Does anyone have any f335 frequently asked questions ?


This is probably really late, but I've attached the last years f335 mark scheme, and I found a document on the popular questions asked
hope it helps

Goodbye uni! Although the exam was slightly easier than f334 I don't feel I done enough to salvage the mess that f334 was 👋

I put HCl for first one and ammonia for second one?
I didn't find it as bad as F334 but this paper was still very nasty I am sure some of the questions branch out of the syllabus

I put ammonia for the second but not HCL :/

I put 107, 4 areas of electron density, one lone pair and three bonding pairs so a trigonal pyramidal shape around the nitrogen
